PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 744,371, dated November 17, 1903.

Application filed July 22, 1903. Serial No. 166,632. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM A. LOGUE, a citizen of the United States, residing at Rathdrum, in the county of Kootenai and State of Idaho, have invented new and useful Improvements in VPrinting-Presses, of Which'the following is a specification.

My inventionpertains to printing-presses;l and it has for its object to provide a printing-f press which is a material simplification of those extant and yet is adapted to do good work with but a minimum amount of effort onV the part of the operator.

The invention will be fully understood from the Afollowing description and claims when taken in connection with the accompanying drawings, forming part of this specification, in which- Figure 1 is a view, partly in side elevation and partly in vertical section, of the printingpress constituting the preferred embodiment of my invention; and Fig. 2, a transverse section taken in the plane indicated by the line 2 2 of Fig. 1.

Similar letters designate corresponding parts in both views of the drawings, referring to which- A is the bed of my improved press, which is provided with the usual legs ct and also with stops a', the said-stops being disposed adjacent to the endsof the bed and having upper sides a2, which describe arcs of circles fora purpose presently set forth. On the bed type-forms b and ink-plates c are suitably secured, the type-forms being disposed `between the ink-plates, as shown in Fig. 1.

B is an impression-cylinder, which carries a central shaft d and is arranged to move longitudinally of the bed A between guide-rails e thereon, Fig. 2. 4This cylinder is provided at'one or both of its ends with spokes f, and it is also provided with aiframevg, preferably integral, disposed on its perimeter and adapted to hold a tympan h solid against the same. To the lower bar of the said frame gis hinged a fly-frame C, which is adapted to be held in theiposition shown in Fig. l by a turn-button 't' and has for its purpose to hold the paper to D D are arms loosely mounted on the shaft d and disposed at opposite ends of the cylinder B, and E E are inking-rollers carried by the said arms and arranged in front and rear of the cylinder B.

In the practical operation of my invention the paper to be printed is placed under the fly-frame C, and the ily-frame is closed and v fastened, after which the operator takes hold lofspokesfof the cylinder and rolls the cylb-t'. e., in the direction opposite to that indicated byarroW-when the described operation is repeated. Incident to the first-described movement of the cylinder the roller E will take ink from one plate c and ink the forms b, while incident to the other or backward movement of the cylinder the roller E will take ink from the other plate c and supply the forms b with the same. The stops a serve to engage the perimeter of the cylinder B and stop the vsame with the cylinderin positions to permit of printed sheets being readily removed from the fly-frame and replaced with fresh sheets.

It will be appreciated ,from the foregoing that notwithstanding the simplicity and cheapness of my improved press and the facility with which it may be operatedthe press is adapted to do accurate and goed Work.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced .in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the s ame. I do not desire, however, to be understood as confining myself to such specific construction and relative arrangement of parts, as such changesv or modificavltions maybe made in practice as fairly fall within the scope of my invention as claimed. Having described ,my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a printing-press, a rolling impressioncylinder, inking-rollers disposed in front and rear thereof, and arms connecting the inkingrollers and the opposite ends of the cylinder, and carrying the rollers, in combination with a bed, having longitudinal guide-rails for the cylinder, a form secured on the bed, and inkbearing plates disposed on the bed, at opposite sides of the form.

2. In a printing-press, a rolling impressioncylinder, and inking-rollers carried by the cylinder and disposed in front and rear thereof, in combination with a bed having longitudinal guide-rails for the cylinder, a form secured on the bed, ink-bearing plates disposed on the bed, at opposite sides of the form, and stops arranged on the bed, adjacent to the opposite ends thereof, and having upper surfaces Which describe arcs of circles, and are adapted to engage the perimeter of the impression-cylinder.

3. In a printing-press, a rolling impressioncylinder having spokes at one end, and carrying a central shaft, arms loosely mounted on and depending from said shaft, and inking-rollers carried by said arms, and disposed in front and rear of the cylinder, in combinarails for the cylinder a form secured on the cylinder, in combination with a bed having longitudinal guide-rails for the cylinder, a frame secured on the bed, at opposite sides of the form, and stops fixed on the bed, adjacent to the opposite ends thereof, and having upper surfaces which describe arcs of circles, and are arranged to engage the perimeter of the cylinder.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
